I just bought a 77 k5. It has a one speed wiper switch on the dash with no washer. It has a floppy blinker lever that doesn't engage turn signals. I want to upgrade all this. I'm wondering if there's a way, while retaining the stock steering column, that I could move the wiper controls to the blinker lever and add a modern amount of wiper speeds. Basically swap in a modern blinker lever. Would it possible to add a washer too? What would that entail? Could I swap in a turn signal switch from a newer k5? Would I need a wiper and washer switch too? How does that work on the newer k5s, are they all in the column? will I need to do anything to the motor? Could it use an upgrade anyways? Lots of questions. If anyone has any answers they'd be greatly appreciated. Thank you.
